Precautions of connecting pipe
● The connection pipe and drainage pipe should be insulated to avoid water
drop-ping due to condensation.
1. Both the indoor side and outdoor side adopt connection of expanding port.
The connection pipe is as shown in the figure, used for connecting indoor unit
and outdoor unit.
2. When connecting the big connection pipe and small connection pipe with the
indoor unit, the big connection pipe and small
connection pipe should be misaligned and the
small connection pipe should be 100mm
longer than big connection pipe.
3. The cut-off valve of outdoor unit shall be closed com-
pletely. For each connection, screw off the screw cap
at the cut-off valve and then connect the port-expanded
pipe immediately (in 5min). If the screw cap at the cut-
off valve has been placed for a long time, dust, moist-
ure and other sundries may get into the pipe, which will
cause malfunction.
Note:
Do not bend the flexible pipe for more than three
times. Do insulation to all connection part of
port-expanded pipe and connection pipe.
